“Thomas Jefferson still survives”

“Can a free government possibly exist with the Roman Catholic religion?{Letter to Thomas Jefferson, May 19, 1821}”

“This society [Jesuits] has been a greater calamity to mankind than the French Revolution, or Napoleon's despotism or ideology. It has obstructed the progress of reformation and the improvement of the human mind in society much longer and more fatally.{Letter to Thomas Jefferson, November 4, 1816. Adams wrote an anonymous 4 volume work on the destructive history of the Jesuits}”

“I almost shudder at the thought of alluding to the most fatal example of the abuses of grief which the history of mankind has preserved - the Cross. Consider what calamities that engine of grief has produced! With the rational respect that is due to it, knavish priests have added prostitutions of it, that fill or might fill the blackest and bloodiest pages of human history.{Letter to Thomas Jefferson, September 3, 1816]”

“I am bold to Say that neither you nor I, will live to See the Course which 'the Wonders of the Times' will take. Many Years, and perhaps Centuries must pass, before the current will acquire a Settled direction... yet Platonic, Pythagoric, Hindoo, and cabalistic Christianity, which is Catholic Christianity, and which has prevailed for 1,500 years, has received a mortal wound, of which the monster must finally die. Yet so strong is his constitution, that he may endure for centuries before he expires.{Letter to Thomas Jefferson, July 16 1814}”

“I do not believe that Mr. Jefferson ever hated me. On the contrary, I believe he always like me: but he detested Hamilton and by whole administration. Then he wished to be President of the United States, and I stood in his way. So he did everything that he could to pull me down. But if I should quarral with him for that, I might quarrel with every man I have had anything to do with in life. This is human nature....I forgive all my enemies and hope they may find mercy in Heaven. Mr. Jefferson and I have grown old and retired from public life. So we are upon our ancient terms of goodwill.”

“We think ourselves possessed, or at least we boast that we are so, of liberty of conscience on all subjects and of the right of free inquiry and private judgment in all cases, and yet how far are we from these exalted privileges in fact. There exists, I believe, throughout the whole Christian world, a law which makes it blasphemy to deny, or to doubt the divine inspiration of all the books of the Old and New Testaments, from Genesis to Revelations. In most countries of Europe it is punished by fire at the stake, or the rack, or the wheel. In England itself, it is punished by boring through the tongue with a red-hot poker. In America it is not much better; even in our Massachusetts, which, I believe, upon the whole, is as temperate and moderate in religious zeal as most of the States, a law was made in the latter end of the last century, repealing the cruel punishments of the former laws, but substituting fine and imprisonment upon all those blasphemies upon any book of the Old Testament or New. Now, what free inquiry, when a writer must surely encounter the risk of fine or imprisonment for adducing any arguments for investigation into the divine authority of those books? Who would run the risk of translating Volney's Recherches Nouvelles? Who would run the risk of translating Dupuis? But I cannot enlarge upon this subject, though I have it much at heart. I think such laws a great embarrassment, great obstructions to the improvement of the human mind. Books that cannot bear examination, certainly ought not to be established as divine inspiration by penal laws... but as long as they continue in force as laws, the human mind must make an awkward and clumsy progress in its investigations. I wish they were repealed.{Letter to Thomas Jefferson, January 23, 1825}”
